.To all whom it may concern:

Be it known that'I, DAVID E. BANGS, of Medford, in the State of Massachusetts, have invented certain new and useful Improvements in Grates lfor Stoves, Furnaces, te., of which the following is a full, clear, and exact description.

This invention consists of a grate for astove or furnace, &c., constructed and 4arranged for operation, all substantially as hereinafter fully described, reference being had to the accompanying plate of drawings, in which- Figure 1 is a plan view of a grate constructed according to this invention, and adapted to fit within a fire-pot or combustion-chamber of a stove or furnace, &c. nal vertical section on line 2 2, Fig. l; and Fig. 3, a transverse vertical section on line 3 3, Fig. I.

In the drawings, A represents a flat rectangular frame, of cast-iron or of any suitable material, and-adapted to itwithin a fire-pot or combustion-chamber of a stove or furnace,

On each sidebar, B, of this frame are up- 4 Snc. wardly-projecting walls G D, connected at the top by a plate, E, closed at their ends F, and forming between them a longitudinal vertical chamber, G. ings or perforat ions, H, establishing communication with said chamber G through the bar,

and each inner wall, C, has a series of vertical openings, J.

I K is a`iiat plate or grate of cast-iron or of any suitable material, having at suitableintervals upwardly-projecting pipes or tubes M, making chambers N, one in each tube, each tube having openings P in its side walls and an opening, O, through its b ottom, the gratev having openings L in it between the several tubes. The grate K is adapted to fIt within the frame A, and on each end Q it has a longitudinally-projecting central pin,'c, which is adapted to lie within its respective bearing b in the end bar, R, of the frame A, and in whichv frame the gratecan swivel or turn on its pins when the attendant desires to clear the grate of ashes, Snc., as usual in grates.

The frame A is of a size to fit closely within the walls of a fire-pot or combustion-chamber or stove or furnace, 8vo., and can be cemented therein to close u p the space between its edges Vand the walls of the fire-pot; or it can be adapted to be removed and inserted at pleasure.

In the use of a grate constructed according Fig. 2 isV a longitudi-A to this invention in a stove, Snc., the coal or coke is placed within the fire-chamber of the stove between the chambered walls, and around and about and over t-he several tubes or pipes, and as the coal or coke burns, air from the outside of the stove passes up through the usual openings, L, in the grate, up through the openings H, into the wall-chambers G, and out at the openings J, up through the openings O, into the pipes or tube-chambers N, and out at their openings P into the fire-chamber, about, around, and among the coal or coke. this arrangement of the wall-chambers and pipe or tube chambers and their respective openings for the circulation of air, a complete andperfeet combustion of thefuelbeing burned in the stove will be accomplished, because of a full and abundant supplyof oxygen se- Byr cured to all portions and particles of the fuel This invention is particularly adapted to' furnaces for locomotives, where perfect combustion and freedom from carbon and smoke are very essential. The bar B has a .series of open- Having thus described my invention, what I claim is l. The combination, with the rectangular frameA, having a chambered sidewall or wallsv provided with elongated slots H and J,

of the section K, tting and swiveled'within the frame A, and provided with a row of vertical tubes or pipes, M, on each side of the center thereof, and having the elongated slots -in the sides and openings in the bottom, substantially as and for the purpose described.

2. The combination, with the rectangular frame A, having a chambered side wall or walls closed at the top and provided with elongated slots H and J, of the Section K, fitting and vswiveled within the frame A, and provided with a series of vertical tubes or pipes, M, situated close to the chambered wall, and having elongated slots opposite to and corresponding with the slots in the chambered wall, substautially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

DAVID E. BANGS.
